What you experienced yesterday was a slightly delayed reaction to the antifungals and probiotic causing a large number of the Candida, or possibly Candida combined with other pathogens, being expelled from your body. This is a good sign since you no doubt lowered the population by a substantial number.
I would stay at the amounts of antifungals you’re now taking for four full days. At that time, if your symptoms have all vanished and you’re feeling well, then you can raise the amounts according to your original plan.
Congratulations on having such success.
